No. of pipes
Also within the general configuration of the device, it is necessary to set the valve
control type, as either local (the valves will be commanded by MAXinBOX FC 0-10V
VALVE itself) or remote (the orders will be sent by MAXinBOX FC 0-10V VALVE bus
to a separate valve actuator, through the KNX bus).
On the other hand, up to four binary outputs are available for the fan speed control,
being possible to configure them as commuting relays (one specific relay for each fan
speed) or as accumulating relays (the more relays closed, the higher the fan speed).
The integrator can also enable, in parameters, an automatic air recirculation in the
cooling mode. This will make the fan remain always on while the current mode is
cooling, even if the temperature setpoint has been reached (stopping the fan may
cause an uncomfortable feeling). Note that orders with a higher priority (such as alarms
configured to switch to fan speed 0) will still prevail over this option.
One parameter is also provided to enable the ventilation mode, being then possible to
switch to that mode through a specific binary object or a scene. The ventilation mode
consists in closing the valve(s) and leaving the fan on. However, the fan speed will
depend on some factors:
If the current mode is cooling, the fan speed will be automatically
determined by the system according to the configuration, unless a specific
speed has been manually ordered (i.e., the fan speed selection is in manual
mode). See section 2.5.3 for details on the fan speed selection.
If the current mode is heating, the fan will remain stopped, unless a specific
speed has been manually ordered (i.e., the fan speed selection is in manual
mode). See section 2.5.3 for details on the fan speed selection.
